Silly rule. Looking good is ageless. You should dress for the occasion, but I feel that if the occasion involves a nice shirt, adding french cuffs might as well be necessary. Particularly if you aren't wearing a tie or anything else that you can use to your advantage. I only own one french cuff shirt, unfortunately, and it isn't close to my favorite. So hard to find them, until I make my own with Custom Label or something. Oh oh oh! If anyone reading this is looking for a good suit that will last them a while, Primer Magazine and Indochino custom suiting are offering a coupon! 10% off any of their suits (which, if it isn't perfectly tailored when received, they'll pay for you to take it to your own tailor - I want the light gray but all my funds are tied up for college, gas, and insurance), a free dress shirt of theirs, and free shipping. Far Most of their prices are just a wee bit more than a department store. Not an advertisement, just thought you oughtta know. Best thing I've learned from Primer, to be honest. Yeah, if I see anyone under 25 wearing a shirt with French cuffs to a baseball game...poser, basically. Looking good is just as much about dressing appropriately for the situation as anything else.
